'Nothing to hide': Man denies role in friend's Fijian prison ordeal

A tip-off from the Australian Federal Police led to two Aussie dads and best friends being charged with importing a huge drugs haul into Fiji - but only one of them now languishes in jail.

Ethan Kai and Shaheed Khan have both claimed their innocence, but the fallout from their arrest couldn't be more different.

Kai, a father of two from Western Sydney, has been sentenced to 15 years in the notorious Suva Prison.

Ethan Kai was jailed in Fiji for smuggling 30kg of heroin into the country, while his co-accused and former friend walked free.

"I came here on holiday, met my friend, and the next minute there was an allegation against me and I got arrested and charged and found guilty on the matter," Kai told A Current Affair in a jailhouse interview.

The charges entailed the importation of 30 kilograms of high-grade heroin inside a shipping container into Fiji, with the drugs ultimately bound for Australia.

Kai was found guilty of importing the drugs, which were concealed in quad bike tyres in the container.

A former building developer, he often flew to Laos for work and caught a flight from Laos to Fiji to arrive at about the same time the container arrived.
